Product Overview
XL-1608SYGC-04 is a XINGLIGHT yellow-green SMD LED supplied in a 0603 package. The device outline is 1.6 x 0.8 x 0.4 mm, with a water colloid transparent lens construction. The datasheet identifies RoHS compliance and a moisture sensitivity level of MSL 3.
At Ta=25°C, the LED is rated for 50 mW maximum power dissipation, 20 mA maximum continuous forward current, 80 mA peak forward current under the stated pulse condition, and 5 V maximum reverse voltage. Optical characteristics at IF=20 mA include 50 to 120 mcd luminous intensity, 565 to 575 nm dominant wavelength, 570 nm typical peak wavelength, 15 nm typical half wave width, and 120 degree typical viewing angle.
Assembly data includes 260°C soldering for no more than 6 seconds, recommended maximum welding at 240±15°C for 6 seconds, and a maximum of two reflow soldering cycles. Storage and handling limits include unopened storage within one year at <=30°C and <=60% RH, and soldering within 168 hours after opening at <=30°C and <=40% RH.

Procurement Notes
When requesting a quote for XL-1608SYGC-04, buyers should confirm the manufacturer, package or case, required quantity, target date code, compliance documents, packing method, destination country and expected delivery schedule.
If alternatives are acceptable, buyers should share the approved vendor list, required electrical or optical limits, package constraints and qualification requirements. Any alternative part should be reviewed by the buyer's engineering team before production use.
For LED and optoelectronic sourcing, brightness bin, wavelength or color temperature bin, forward voltage range, viewing angle, moisture sensitivity level and soldering process limits may affect final selection, availability and lead time.
